WINDOW \A'ppneatmn med January 4, 1930. serial No. 418,498.

My invention relates to an improvement in windows more especially windowsto be used in houses or buildings, and has forits primary object the provisionof a means ior supporting the lglass panes of a. window to overcome the neceity of using a sash, about the pane. My window isthus of a type in which the sash ordinarily encasing the window has been eliminated. My invention is designed for the purpose of improving the appearance of thewindows of a building by eliminating bulky window sashes, and functions to increase materlally the amount of light entering through any slze Window. By substituting window an equal visible area of glass, the amount of light passing through the window is materially increased. y

It isa feature of my invention to provide a frame `for my window. which is adapted to be anchored securely into the building structure to form a tight weather-proof joint between the window frame and the building. This is important in View of the common 25 knowledge that shrinkage of ordinary wooden window frames, and careless fitting of these frames into the building structure often permits a draft of air to enter about the frames in ordinary buildings where wooden frames are used. Y

It is an added feature of my invention that although my frames are anchored securely into the building structure, and fit tightly to prevent the danger of draft about the frame, they inay be inserted into' window openings `which are larger than is necessary to accommodate the frame. In this way it is apparent that more clearance may be left for the frame, and less precision be necessary in the construction of the Window openings, speeding the construction of the building Without sacrifie'- ing a weather-proof casing.

It is a feature of my invention to provide grooves for t-he Window panes formed of metal in which the sides of the glass panes, encased in a metal casing, may slide. This construction forms a combination as eifective as 'weather stripping, and at the same time eliminates the window sash. The window thus formed is very effective in preventing or the-sash of the -in a Ventilating means which is provided between the window panes. Between the usual upper and lower window panes I provide `a ventilator which may be operated to allow air to enter without opening the anes of the window, preventing a draft o air entering the room, andat the same time acting to di use the entering air. This ventilator acts as the meeting rail between the lower edge of the upper panel and the upper edge ofthe lower pane, and is pivotall supported at the ends transversely across t e frame, in a manner to allow the ventilator to tilt to permit a ventilation into the room without the usual disadvantage of having rain beat in through an open window as it does with the ordinary type of window opening at the top u out the use of putty or special tools and may .o

easily be done by anyone by following simplel directions. Furthermore, no special glass is required, and no holes need be bored in the glass. T he meeting rail may be easily removed or inserted in place.` Very little time is required to change a window pane or to repair a broken glass. The simplicity of construction and the advantages in use over the common type of window mark my `window as an economical improvement.

These objects, together with other details and features of my windo'w will be more clearly and specifically defined in the followin g specification and claims.

In the drawings forming part of this speci. fcation:

My window is formed with an upper pane A and a lower pane B, adapted to slide up and down in grooves 10 and 11 formed in the frame C. These grooves 10 and 11 extend in parallel relation the length of the frame. The upper pane A is adapted to slide in one groove' 10, and the lower pane slides iny the other groove 11, and the sliding of these panes acts to open or close the window. These grooves l1() and 11 are formed 4in a side plate 12 whichhas flanges 13 and 14 adapted to extend into, and anchor to, the

structure of the building. In inserting my window frame, even if the window opening has been made too large, the side plates 12 may be secured closer to, or farther fromY the Aspacing member 15, as desired, in order that the two side plates 12 be the correct distance apart. v The flange 14 is secured directly:to the reinforcing members 16 about the window opening and the outer casing member 17 attached over the iange, forming a weather-proof joint. The inner fiange 13 is attachedto the spacing member 15, and the inner casing 18 is fastened over the joint and extends over the edge of the inner wall 19, which is ordinarily a plastered surface. Thus I provide a rigid, tight construction regardless of the accuracy with which the window openings are constructed.

Within the grooves 10 and 11, I provide caslngs 20, adapted to slide with and contain the side edges 22 of the glass panes A and B. This casing is in the form of a rectangular tube, having a slot 23 in one .side thereof, and having inwardly turned anges 24 on each side of this slot 23 between which the glass of the panes A and B isadapted `to be positioned. These glass panes A and B are held in place with the side edges 22 within the casing 20 by V-shaped sprlng clips 25 which are inserted between the edges 22 of the glass panes and the inner wall of the ,37 to form' a tioht closure.

casing 20. The spring clis 25 are formed as shown in Figures 6 an portion 26 adapted to bear against the top or bottom ed e 27 of the glass pane, a side portion 28 a apted to bear a ainstuthe side edge 22 of the glass pane, an a spring arm 29 at an acute angle with the side portion 28, adapted to force the side portion 28 firmly against the edge 22 of the pane. I The spring arm 29 is shorter than the side portion 28,

7, with an end and when inserted the spring clip is wedged into the Casin 20 until the end 30 of the spring arm ,29 ecom'es locked behind a air of inwardly projecting shoulders 32. our of these clips 25 are used on each pane, one at the bottom and another at the. top of each casing 20, and when in place, these cli s hold the pane firmly in place within t e casings 2O so that the pane and casings slide up and down in the grooves 10 and 1l as a unit.

To facilitate the lifting of the panes A and B, and to hold them in position when raised, I rovide a pair of spring balances 33 for each) pane A and B. These s ring balances 33 are mounted at the top o the win-- dow frame, one on either side of the frame for each pane. Metal tapes 34 or lifting straps extend down from each of these spring balances 33 and are attached to hooks 35 upon the sprinF clips 25. As these balances 33 compensate ?or 4the weight of the windows, the windows may be easily raised or lowered by means of the lhandles 36 which are attached into the Casin s 2O on the inner side of the panes A and f When the panes A and B are in closed position, the upper edge of the pane A extends into a channel 37-formed in the top of the frame C. This channel 37 has slopin sides, andthe glass pane'A wedges into the c annel The lower edge of the pane Blbears against a spring strip 38 which is inserted between the stool 39 and the sill 40 of the `frame C to form a tight joint.

The meeting rail 42 is detachably pivotally attached to the side plates 12 of theframe C. Being detachable, this meeting rail may be easily assembled into place, or detached when desired.

This ventilator or meeting rail 42 is preferably formed of a wooden strip 43 to which the pivots are attached, an insulating composition strip 44v and a sheet metal covering strip 45, adapted to rovide a spring closure for the lower edge o? the upper pane A, and a cover for the insulating strip 44.

The upper edge of the lower pane B extends into the insulating strip 44 between the end of the metal covering 45 and the wooden base member 43. A lock 46 holds the meeting rail 42 in closed position when desired, and when opened, the space between the panes provides a Ventilating means to al- J of air in the room` low air to enter the building. The air in entering through the ventilator, is directed into tie room in an upwardly direction, tending to prevent any direct currentor draft and acting to. diluse the incoming air.

My ventilator could also be constructed in the manner illustrated in Figures 7 to 10. In this modification one strip of metal 49 is `curved to form a tube-like portion 50,

Within the ends of which the pivots for opening and closing the meeting rail may be positioned. A second strip 51 is formed to provide a trough 52 for accommodating the lower edge of the pane A, extendsl to form the upper surface 58 of the meeting rail, and is curved to form a housing 54 for the window lock. Secured between the strips 49 and 51l is a pad 55 of felt or other insulating material against which the upper edge of the pane B contacts.

The lock is formed of a pair of levers 56 and 57 which are substantially wedge-shaped on one end 58, so that when operated, the wedge the meeting rail tightly against botii panes A and B. In the opposite ends of these levers 56 and 57 are formed slots 59, having one smooth edge, and one edge bearing teeth '60. The teeth 60 are formed on the upper edge of the slot 59 on one lever 56, and are formed ont-he lower edge of-the slot 59 on the other lever 57. A pinion 6l extends through the slots 59, the shaft of which is attached to a handle 62. By twisting the handle ,62, the Apinion engages in the teeth 60forcing the lever 56 in one direction, and the lever 57 in the opposite direction, to force the wedge-shaped ends into or out of the frame C. Suitable lugs 63 prevent the levers 56 and 57 from twisting and support them within the housing 54.

I have provided a window which is easily repaired when a pane is broken without the need of special tools or mechanical knowlinserting a tool such as a screw driver or the like between the inner wall of the casing 20 and the spring arm'29 of the spring clip 25 in the engaging recess 47 formed for that urpose in the end 30 of the spring arm 29,v orcing the end 30 of the spring arm 29 out of engagement with the shoulders 32, and releasing which permits withdrawal of the spring clips 25. If the pane A or B is to be taken out, -the clips 25 may be removed, and the pane is permitted to extend into one of the slots 23 until the other edge of the'pane A or B is free of the slot 23 on the opposite side of the frame. When one side edge of the pane is free, the glass may be easily removed from the other slot, and from the frame. Inserting glass is merely a reversal of this action.

I have provided a window of simple con- C" struction, easy to manufacture and easy to inedge. The pane may be easily removed by stall and use. My window is of weatherproof construction, having tight connectin Joints. My window is easily operated an will not stick or bind in damp weather. My window provides a means of ventilation even in violent rain storms and includes a means of ermitting the entrance of air without raising or lowering the panes to Lallow the entrance of rain. Furthermore, I have constructed a Window which is easily and quickvWithout departing from the spirit of the invention.
